graph
node.remove
Remove a graph node and its edges.
strata graph remove-nodedb.graphs.remove_node(graph: 'str', node_id: 'str') -> 'Any'wire graph_remove_node
Removes a node and every edge incident to it in one commit. Removing a node that does not exist is not an error: the acknowledgement reports `deleted: false`.
Successful mutations return an acknowledgement of the outcome: for a state-changing write, the affected target with the mutation effect and commit facts; for mutations that produce a domain result (such as a branch or a promotion outcome), that result object.
